We’ve published posts in the past about why recycling gold is socially responsible. Recycled gold doesn’t have to be mined, and mining pollutes air and water and burns fossil fuels. And then there’s the fact that recycled gold is not dug from the earth by underpaid, exploited workers. Of course, it is possible that the gold that we recycle from computer motherboards, old jewelry and other sources does have a “dirty” past – because gold doesn’t have DNA, it is impossible to know whether it originally came from a mine in Africa or from ancient amulets that were stolen from the Aztecs. But even if that is the case, the gold that we recycle today is generations removed from any dirty sources and less closely linked to environmental or societal ills.
